Lincoln MKX yellow engine light is on without blinking and vehicle is running fine on Lincoln MKX

Some Lincoln MKX owners report experiencing a yellow check engine light that remains on without blinking, indicating minor issues such as a loose gas cap. This light may also be triggered by sensor or emissions problems, which can be diagnosed using a fault code stored in the engine control unit and retrieved with an OBD-II scanner. Additionally, some owners find that the check engine light serves as a service reminder for routine maintenance. Despite the vehicle running fine, it is advisable for owners to have the check engine light inspected by a mechanic to rule out any underlying issues that could worsen over time, as ignoring this warning could lead to more serious problems in the future.
